RacketCon 2026 is scheduled for Saturday, with doors opening at 8:30 a.m. PDT and talks beginning at 9 a.m. The event is open to people interested in Racket, with a livestream and live chat for remote audiences; recordings are expected on YouTube after the conference.

RacketCon 2026 is scheduled for Saturday, bringing together people interested in the Racket programming language for a day of talks, with an in-person gathering and a livestream for remote viewers. The published schedule lists doors opening at 8:30 a.m. PDT and the first talk at 9 a.m.; the conference says recordings will be posted on YouTube sometime after the event.

The program opens with “On Notation” at 9 a.m., presented by Pat Hanrahan, the Stanford University professor emeritus who helped lead the design of RenderMan at Pixar, co-founded Tableau and received the 2019 ACM Turing Award. A 10 a.m. break precedes the technical talks, which begin at 10:30 a.m.

Fred Fu, a PhD candidate at Indiana University, is scheduled to discuss type inference for untyped languages. His talk covers an ongoing prototype that combines occurrence typing and algebraic subtyping to address cases where Typed Racket struggles to infer types in code generated by macros. The published description says programmers can face pressure to rewrite macros in Typed Racket when generated code contains lambda parameters that cannot be annotated directly.

At 11:10 a.m., Northwestern University PhD student Lucas Myers will present Pille, a Rhombus-based language project using an LLVM-based compiler to target low-level and high-performance programming. After lunch, which the conference says will be provided, Mike Delmonaco will discuss Treason, a prototype intended to maintain IDE services when errors prevent complete macro expansion. A 2:10 p.m. talk by University of Utah Associate Professor Pavel Panchekha will cover Herbie, a compiler that seeks more accurate floating-point expressions. The posted schedule lists JJ’s talk on effect handlers in the Racket and Guile Scheme library cio at 3:30 p.m.

A Program Focused on Language Tools

The schedule reflects the Racket community’s interest in both language design and practical programming tools. Talks address challenges familiar to developers working with macros, types, IDE support and floating-point calculations, while Pille explores applying extensible-language ideas to lower-level programming. These are research and project presentations, not announcements that the tools are finished or broadly available; the descriptions identify Pille and Treason as projects or prototypes.

Remote access also broadens the event beyond those able to attend in person. RacketCon says viewers can follow the livestream and use live chat, and may buy a remote participation ticket to support the stream. That gives people outside the venue a way to take part, though the source does not provide the stream link or ticket price in the supplied details.

How Saturday’s Schedule Is Set

RacketCon describes itself as a public gathering intended to support an inclusive community around Racket and engage both Racket users and the wider programming world. The event page invites registration for the 2026 conference and mentions discounted early registration before Sept. 13. The supplied information does not state the year associated with that deadline or whether the discount remains available.

The organizers say the conference will be streamed, as in previous years, and that recordings will appear on YouTube sometime afterward. The page also points readers to presentations from earlier RacketCons. This year’s listed sessions move from notation and type inference in the morning to macro-aware IDE services, floating-point accuracy and effect handlers in the afternoon.

““A public gathering dedicated to fostering a vibrant, innovative, and inclusive community around the Racket programming language.””

— RacketCon organizers

Date and Remote Access Details

The source identifies the event as happening Saturday but does not give the calendar date. It also does not include the venue, livestream URL, remote ticket price or instructions for joining the live chat. The page mentions a discounted registration deadline of Sept. 13, but the supplied text does not clarify the year or the discount’s current status.

Several sessions describe work in progress, including Fu’s ongoing type-inference prototype and the Treason prototype. The conference schedule does not establish what results the talks will report, whether the projects will be released, or when any tools might become available. The organizers have not given a specific date for YouTube recordings.

Saturday’s Talks and Recordings

The next milestone is the conference itself: doors are listed for 8:30 a.m. PDT Saturday, followed by the 9 a.m. opening talk. Attendees and remote viewers can follow the posted program through the afternoon, with lunch scheduled at 11:50 a.m. and the final listed session at 3:30 p.m.

People planning to watch remotely should consult the RacketCon event page for the livestream and ticket information, which are not included in the supplied source text. After the conference, organizers say they will make recordings available on YouTube, but have not announced a posting schedule.
